When I arrived in Santa Barbara, Doctor Hamilton was
about to remodel, or rather reconstruct, his animal
cages and laboratory. This gave us opportunity
to adapt both to the special needs of my experiments.
The laboratory was finally located and built in a
grove of live oaks. From the front it is well
shown by figure 10 of plate III, and from the rear,
by figure 11. Its location was in every way satisfactory
for my work, and in addition, the spot proved a delightful
one in which to spend one’s time.

Figure 12 is a ground plan, drawn to scale, of the
laboratory and the adjoining cages, showing the relations
of the several rooms of the laboratory among themselves
and to the nine cages. Although the construction
was throughout simple, everything was convenient and
so planned as to expedite my experimental work.
The large room A, adjoining the cages, was used exclusively
for an experimental study of ideational behavior by
means of my recently devised multiple-choice method.
Additional, and supplementary, experiments were conducted
in the large cage Z. Room D served as a store-room
and work-shop.

The laboratory was forty feet long, twenty-two feet
wide, and ten feet to the plate. Each small cage
was six, by six, by twelve feet deep, while the large
compartment into which each of the smaller cages opened
was twenty-four feet long, ten feet wide, and twelve
feet deep.

OBSERVATIONAL PROBLEMS AND METHODS

My chief observational task in Montecito was the study
of ideational behavior, or of such adaptive behavior
in monkeys and apes as corresponds to the ideational
behavior of man. It was my plan to determine,
so far as possible in the time at my disposal, the
existence or absence of ideas and the role which they
play in the solution of problems by monkeys and apes.
I had in mind the behavioristic form of the perennial
questions: Do these animals think, do they reason,
and if so, what is the nature of these processes as
indicated by the characteristics of their adaptive
behavior?
